|
Acceleration |
The rate at which an object changes its velocity |
|
|
Acceleration due to gravity (g) |
Acceleration due to gravity in the absence of air resistance. |
|
|
Air resistance |
A friction-like force that opposes the motion of objects that move through the air |
|
|
Average acceleration |
Average rate at which an object changes its velocity; shown by the slope of a velocity-time graph |
|
|
Change in velocity |
Change that occurs when the speed of an object changes, or its direction of motion changes, or both; calculated by subtracting the initial velocity from the final velocity |
|
|
Constant acceleration |
Velocity changing at a constant rate |
|
|
Deceleration |
Acceleration that is opposite to the direction of motion; a decrease in the speed of an object |
|
|
Gravity |
Attractive force between two or more masses; causes objects to be pulled toward the center of Earth |
|
|
Velocity-time graph |
A graph of an object's velocity during corresponding time intervals; time data are plotted on the horizontal axis (x-axis) and velocity data are plotted on the vertical axis (y-axis). |
